I call using VOIP as I am not always in the USA- However, some locations that show 5 MB or more upload, I have no issues. However sometimes when you test in the morning it is fine, but when you test later it drops down to 300Kbps- why is that? Does Internet have the same shared lines (party lines) like telephones had back in the 70's and 80's?
Why such a huge jump down?
Thanks for any advice as I rely on making these calls and if lower than 1 MB everyone has trouble hearing me.
